Hi, I think I have got myself into a pretty unique situation which I can't find any documentation on. i have just bought an X1800 master card 512mb because it was cheaper than the X1800XT, and seemed to have the same specs. It then dawned on me it wasnt just crossfire ready, but it was the master card. The problem is, I have an old Intel 915G based motherboard, which of course only has the one pci-e 16x slot. My question is, will it work on its own in a non- crossfire board? Thanks
